Title: Electromagneto-optical device
Inventor: TADA HIROAKI
IPC: G02F1/19
Filed: 1987-08-04
Abstract: PURPOSE:To improve a light control function by using fine anisotropic dipolar particles which are coated with a metal or org. metal which absorbs or reflects light of a visible-near IR region as fine anisotropic dipolar particles. CONSTITUTION:The fine anisotropic dipolar particles to be used are coated with a semiconductor such as titanium dioxide on at least the surfaces and further, the material which strongly absorbs or reflects the light of the visible- near IR region is deposited on the fine anisotropic dipolar particles coated with the semiconductor by using a method such as photodeposition method. Metals having the oxidation-reduction potential theoretically nobler than the oxidation-reduction potential in the conductor position of semiconductors if a suitable reducing agent is added thereto are satisfactory as the metal which can be deposited of the fine semiconductor particles by the photodeposition method. The light control function of the suspension element is thereby greatly improved.

Title: Sensorless controller for synchronous motor
Inventor: YOSHIDA KOSAKU
IPC: H02P6/16
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain a sensorless controller, which can be reduced in cost by reducing the number of used expensive current sensors to the minimum, and at the same time, can easily perform sine wave control without having to input the parameters, etc., of a synchronous motor. SOLUTION: A sensorless controller calculates speed electromotive forces eu, ev, and ew, based on the three-phase voltage values Vu-fb, Vv-fb, and Vw-fb of a synchronous motor 0 detected by means of a resistor 4 and voltage command values Vu, Vv, and Vw and an angle θ of the rotor of the motor 0, based on the electromotive forces eu, ev, and ew and performs sine wave control on the motor 0 based on the angle θ. Therefore, cost of the controller can be reduced, because the controller can be constituted by using only one expensive current controller for current control. In addition, the sine wave control can be performed more easily, because it becomes unnecessary to set the parameters (resistance value and reactor value) of the motor 0.

Title: Method for injecting liquid crystal
Inventor: ICHINOSE HIDEO
IPC: G02F1/1341
Filed: 1991-08-06
Abstract: PURPOSE:To prevent the splashing of a liquid crystal material by stirring the liquid crystal material simultaneously with execution of a pressure reduction, then injecting the liquid crystal material into a liquid crystal element. CONSTITUTION:A liquid crystal injecting tray 10 is provided with a groove for housing the liquid crystal material into the position of the oriented film injection hole of the liquid crystal element 20. The liquid crystal material is filled into this groove and evacuation is started while the liquid crystal material is kept stirred by a stirring rod 11. The liquid crystal injection hole is eventually opened into the liquid crystal material when the liquid crystal element 20 is mounted to the liquid crystal injection tray 10 after the liquid crystal material is sufficiently defoamed. The liquid crystal material is injected of itself into the liquid crystal element 20. Namely, the inside of a vacuum chamber is evacuated to the vacuum from the atm. pressure in the case of subjecting the liquid crystal material to the evacuation in this chamber and, therefore, the bubbles are gradually generated from the case of a low vacuum degree if the liquid crystal material is simultaneously stirred. The generation of a high vacuum and the rapid generation of the bubbles do not arise and the splashing of the liquid crystal material into the vacuum chamber does not arise, unlike the case the liquid crystal material is left standing without stirring.

Title: Heating-cooker
Inventor: OKADA KAZUICHI
IPC: F24C15/10
Filed: 1982-11-08
Abstract: PURPOSE:To reduce ventilation resistance which is applicable when air passess through a preventive plate for invasion of a foreign matter and to make the foreign matter difficult to invade, by a method wherein a rib is formed into either an inclined straight line or a circular arc state to a straight line radiated from a rotary center of a cooling fan provided in the vicinity of an air hole. CONSTITUTION:When a fan 11 is revolved and air is sucked into an apparatus body, an air flows around the fan 11 is apt to be absorbed in a swirl state as shown by an arrow. In this instance, as a rib 12-b is in a circular arc state and is tilted to a straight line radiated from a rotary center B of the fan 11, ventilation resistance of the rib 12-b becomes small, an air quantity to be sucked into the apparatus body is increased and simultaneously with an improvement in cooling efficiency generation of a noise is controlled also. In addition to the above, prevention of an invasion of a foreign matter can be contrived as a gap C between mutual ribs 12-b becomes narrower even under an identical number of ribs 12-b as comparing the gap C with that wherein the ribs 12-b are not tilted due to a structure that the rib 12-b is tilted to a straight line radiating from a rotary center B of the fan 11 when the foreign matter is moving to pass through the gap of the ribs 12-b.
